chirp is a one-of-a-kind wireless beacon designed specifically for the outdoor adventures of geocaching. Affordable, durable and waterproof, chirp can communicate with, and be programmed by, any compatible wireless-enabled Garmin handheld (sold separately). chirp stores hints, multicache coordinates, counts visitors and confirms the cache is nearby. chirp is password protected and has a battery life of up to one year.

Get & Store Hints

chirp can be programmed by any compatible wireless-enabled Garmin handheld to store geocaching hints and other information. When other geocachers arrive near your cache, they’ll be alerted that the cache is nearby, and then they’ll be able to access the hints you’ve loaded into chirp. And when you return, chirp will tell you how many visitors have been to your cache.

Setup a Multicache

With chirp, setting up and maintaining a multicache has never been easier. Using your compatible Garmin handheld device, chirp automatically transmits program coordinates so other cachers can find each stage of your multicache. Or if you’re on a multicache, chirp lets you download coordinates. So there’s no need to manually enter numerous sets of complex coordinates – there’s just one simple touch and you’re on your way to the next stage.Built To Cache — Built to Last

chirp was designed by geocachers, so it’s built to take the rigors of the outdoors. Plus, chirp is password protected, so you’re the only one with programming powers. chirp has a battery life of up to a year and the battery is easy to replace, plus chirp features a cache-perfect, small size and is durable and waterproof.

It looks like you leave it at a waypoint and when your GPS gets within range, it will receive additional data such as a clue or coords of next waypoint.It would not necessarily need to be physically found. It could possibly be up a tree near a cache and say "Look under rock" to help you find the cache, or else give you the next waypoint in a multi.That's my understanding anyway Firmware Updates were made available this morning and can be installed using Webupdater.GPSMAP 62/78 (2.70)Oregon x50 (4.00)Dakota (3.50)Oregon x00 (4.10)

I would be disappointed if groundspeak allow it to be used as stages of a multi as it limits the finders to someone who owns the compatible device. Unless there is also a physical container with the next stage info as well so everyone has a chance (it just makes it easier for those people with the right gear, they don't need to physically find all the waypoints, just get close).

If you want to place a Chirp-cache you need a second way for non-garmin users.

I didn't see anything official in that thread, but I may have missed it...

There was a reviewer/mod's opinion, but that's all it is until Groundspeak makes a pronouncement.

Personally, I think this probably does go against the commercial guideline, the same way I would consider something that can only be found using an iPhone app to be commercial. (It gets murky if you think about Android/WinMobile apps, since there's multiple vendors of hardware...)

It's a shame it's being treated as a way to sell high-end GPSrs instead of a wide-appeal product in its own right. A low-power Bluetooth device would be more fun. Hmmm....
